Due to high rate of corruptions in developing states, government policies diversified governmental services from offline to virtualized perspective to expose accessibility, transparency, accountability and accessibility through mobile government. Deployment of such ICT tool also exposed a unique opportunity for the recovery of the public confidence against government which has damaged due to corruption activities in country. Virtualization of the government services became compulsory due to high rate of corruption that occurred in the economic context and it became a serious obstacle for economic development of developing states. The virtualized services aimed to harmonize governmental services into mobile platform in order to become more transparent to the public. This research paper comparatively investigates the mobile government services that are located in Malta and Singapore which are classified as developing countries. The criteria of the comparison have done based on demographic structure of the country, M-government policies and ICT infrastructure of the country. The findings of this study exposed the impact of e-government practices and differences between them in terms of applicability and provide a specific point of view for m-government adoption policy.展开更多

Then under the condition of m-irreducible, the relationship of recurrent and positive recurrent between two states is studied. We also give several conditions that can imply a state is recurrent and positive recurrent. And then the period of a state is discussed and we obtained that under the condition of m-irreducible, for any two states in x, they have the same period.展开更多

Looking at the problem from this novel viewpoint was rewarded by a rather unexpected result, namely that the gap labelling method of integrated density of states for three dimensional icosahedral quasicrystals is identical to the previously measured and theoretically concluded ordinary energy density of the universe, namely a mere 4.5 percent of Einstein’s energy density, i.e. E(O) = mc2/22 where E is the energy, m is the mass and c is the speed of light. Consequently we conclude that the missing dark energy density must be E(D) = 1 - E(O) = mc2(21/22) in agreement with all known cosmological measurements and observations. This result could also be interpreted as a strong evidence for the self similarity of the geometry of spacetime, which is an expression of its basic fractal nature.展开更多
